Session on page

[oz11]

 

Hey.. i have this code. Though the form is shown on the page after entering the password, and its gone as desired when I reload the page.. how do I get it to not show on the next page before having to reload??

$room = $_GET['room'];
$salt = 444422;
if($_SESSION['in_chat']!=$room.$salt){
    $stmt = $pdo->prepare("SELECT pass_code FROM `chatrooms` WHERE name =?");
    $stmt->execute([$_GET['room']]); 
    $pass_checker = $stmt->fetch();

    $hash = $pass_checker['pass_code'];
    if($hash!=null AND $_SESSION['in_chat']!=$room.$salt){
    ?>
        <form action="" method="POST" name="passcheck">
        <input type="password" name="password_"><input type="hidden" name="chat_pass"><input type="submit" value="Submit"></form>
    <?php
    }   
    if(isset($_POST['password_'])) {
        if(!password_verify($_POST['password_'], $pass_checker['pass_code'])) {
            echo "Wrong password";
            exit;
        }  else{
           $_SESSION['in_chat'] == $room.$salt; 
        }
    } else{
        exit();
    }
}

Note: "salt" is just there so i can test the sessions without resetting.

Thanks!

Dunno how helpful this is, but if I were you I would put all the relevant PHP code before the HTML so I didn't keep breaking in and out of it.

I suppose the reason why the form is showing on the next page is that it's in the HTML, but someone with more experience may have a better solution.
